Quartus Prime Lite - Difficulties with simulation

I think I'm having the same problem with ALTPLL RTL simulation. I have to believe this is something simple, but I'm not getting the PLL to put out a clock.

Testbench code:

`timescale 1ns / 1ps

module TB_1();

// Inputs

reg ClkIN;

reg ResetN;

wire [3:0] SignalOut;

testpll testpll(

.ClkIN(ClkIN),

.ResetN(ResetN),

.SignalOut(SignalOut)

);

initial begin

ClkIN = 1'b0;

# 5 ClkIN = 1'b1;

forever

begin

//Create a 25MHz clock

# 20 ClkIN = !ClkIN;

end

end

initial begin

$display($time, " << Starting Simulation >> ");

# 1 ResetN = 1'b1;

//Apply Reset twice

# 150 ResetN = 1'b0;

# 1500 ResetN = 1'b1;

# 1500 ResetN = 1'b0;

# 1500 ResetN = 1'b1;

# 1000;

$display($time, "<< Simulation Complete >>");

// $stop;

end

endmodule

No errors or warnings in modelsim. I have attached a couple of screencaps of the waveforms. There should be plenty of time to lock.

FPGA code:

module testpll (

ClkIN,

ResetN,

SignalOut );

input ClkIN;

input ResetN;

output [3:0] SignalOut;

reg [3:0] SignalOut;

wire SysClk;

always @ (posedge SysClk or negedge ResetN)

begin

if (!ResetN)

begin

SignalOut <= 0;

end

else begin

SignalOut <= SignalOut+1; //simple 4-bit free-running counter w/ ACLR

end

end //end always

/*

* PLL block instantiation. Take in 25 MHz clock and generate internal 135 MHz clock

*/

Imelda_PLL Imelda_PLL(

.areset ( !ResetN ),

.inclk0 ( ClkIN ),

.c0 ( SysClk ),

.locked ()

&nbsp;);

endmodule

The PLL is from the project that I originally had the issue with, so I cut it down to this simple example. The PLL simply takes in 25 MHz and cranks it up to 135 MHz. I can zip the folder and send it if you like.

This is targeted to a 10CL006-8 in TQFP. Quartus Prime Lite Edition V17.1.1 Build 593 12/11/2017

Any thoughts or suggestions? Until I have a clock it's kinda tough to do much simulation.

Thanks much
